Abstract: A computing device obtains a Network Abstraction Layer (NAL) unit header of a NAL unit of the multi-layer video data. The NAL unit header comprises a layer identifier syntax element having a value that specifies an identifier of a layer of the NAL unit. The layer identifier syntax element comprises a plurality of bits that represent the value within a defined range of values. A requirement of the bitstream conforming to a video coding standard is that the value of the layer identifier syntax element is less than the maximum value of the range of values.

Abstract: A video decoder receives a value for a first syntax element representing whether a dependency type syntax element for a current layer is signaled, wherein the dependency type syntax element identifies a type of dependency of a current layer relative to a reference layer; and in response to the value for the first syntax element indicating that the dependency type syntax element is not signaled determines that the type of dependency of the current layer relative to the reference layer is a predetermined type and decodes a block of the current layer using inter-layer prediction conforming to the predetermined type.

Abstract: Techniques are described for signaling of representation format information in multi-layer bitstreams. Representation format information is signaled using representation format syntax structures included in a video parameter set (VPS) for a video sequence in a multi-layer bitstream. When syntax elements associated with the representation format syntax structures are not present in the VPS, a mapping of representation formats to layers in the multi-layer bitstream may be inferred. According to the techniques, in the absence of the syntax elements, a video decoder infers which of the representation format syntax structures is applied to which of the layers in the bitstream based on a number of the representation format syntax structures included in the VPS for the video sequence. By basing the inference on the number of representation format syntax structures for the video sequence, the inference may be accurate for the type of multi-layer video extension used in the multi-layer bitstream.
